Marantz HDAM TechnologyThe PM8005 features Marantz HDAM (Hyper Dynamic Amplifier Module) technology, which consists of precision discrete selected circuit elements on a compact sub-board, instead of conventional op-amp integrated circuits. Multiple HDAM units are employed, including HDAM-SA3 and HDAM-SA2 versions that provide gain and buffering functions, to deliver dynamic and detailed sound quality. The PM8005 features current feedback technology for low distortion and wideband response, along with life-like musicality.High-Current Power SupplyThe robust power supply features a high-current toroidal main power transformer that is rated at 625VA, providing extra power to the amplifier stage in order to handle demanding short-term peaks. High-current Shottky barrier diodes in the rectification stage are rated at 20 amps, with the ability to handle up to 180 amps peak current, providing sufficient power reserve to handle virtually any loudspeaker load.Fully Discrete High-Current Output StagesThe PM8005 is equipped with multiple high-speed, high-current power output devices that are each rated at 14 amps of current output capability, providing a high amount of dynamic headroom, along with compatibility with lower impedance loudspeakers. For optimum heat dissipation, the PM8005 is equipped with solid aluminum power amplifier heat sinks, with a combined total radiating area of 326 square inches, eliminating the need for fans. The PM8005 is rated at 70 W per channel into 8 ohms, and 100 watts per channel into 4 ohms, for compatibility with a wide range of loudspeakers.Solid Chassis ConstructionFor stability and protection from induced vibrations, the PM8005 features a rugged chassis design, which includes a triple-layer bottom plate. To eliminate distortion from stray magnetic fields, the high-current toroidal main power transformer features double shielding.Versatile Pre-Amplifier FunctionsThere are 6 line level inputs to handle a wide range of sources, including a dedicated phono input (MM) that features discrete topology to deliver high fidelity from your favorite vinyl recordings.

Marantz HDAM Technology

The PM8005 features Marantz HDAM (Hyper Dynamic Amplifier Module) technology, which consists of precision discrete selected circuit elements on a compact sub-board, instead of conventional op-amp integrated circuits. Multiple HDAM units are employed, including HDAM-SA3 and HDAM-SA2 versions that provide gain and buffering functions, to deliver dynamic and detailed sound quality. The PM8005 features current feedback technology for low distortion and wideband response, along with life-like musicality.

High-Current Power Supply

The robust power supply features a high-current toroidal main power transformer that is rated at 625VA, providing extra power to the amplifier stage in order to handle demanding short-term peaks. High-current Shottky barrier diodes in the rectification stage are rated at 20 amps, with the ability to handle up to 180 amps peak current, providing sufficient power reserve to handle virtually any loudspeaker load.

Fully Discrete High-Current Output Stages

The PM8005 is equipped with multiple high-speed, high-current power output devices that are each rated at 14 amps of current output capability, providing a high amount of dynamic headroom, along with compatibility with lower impedance loudspeakers. For optimum heat dissipation, the PM8005 is equipped with solid aluminum power amplifier heat sinks, with a combined total radiating area of 326 square inches, eliminating the need for fans. The PM8005 is rated at 70 W per channel into 8 ohms, and 100 watts per channel into 4 ohms, for compatibility with a wide range of loudspeakers.
